To all whom itonag concern:

Be it known that I, CLARENCE T. OLSON, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Ball Bearings, of which thefollowing is a specification.

This invention relates to ball bearings and more particularly to meansfor securing the inner race-member of a ball hearing from turning on ashaft passing therethrough while the outer race-member is held in a,

housing in a well known manner. This housing may be used as a hanger boxwhich ordinarily encloses two bearings.

The invention is fully described in the following specification andshown in the accompanying drawings, in which:

Fi e 1- is a partial horizontal section through a hanger boxembodyingfthe invention;

of the same; and

Figures 3 and 4 are transverse sections on; 3 and 4 respectively ofFigs. 1

' 'collar. 28 will cause the two engaging ecthe lines and 2. y

In Figs. 1 and 3 is shown an embodiment of the device as applied to a.radial ball hearing having inner and outer race-members 10 and 11 witha. set of balls or other antifriction members rolling in suitableraceways therein.

The inner race-member 10 is loosely mounted upon a shaft 13 which isusually The inner racemember is preferably wider than the outerrace-member 11 so as to project beyond it as shown in Fig. 1 and has aneccentric groove 14 formed therein, which is adapted to hold a splitring 15, the outer surface of which will therefore be eccentric to theshaft 13. A collar '16 is placed on the shaft 13 adjacent the innerrace-member 10 and is secured upon the-shaft by means of a setscrew 17.This collar has a bore 19 which is eccentricto the axis of this shaft13'but concentric with the outer surface of the ring 15,which it loose1y surrounds.

It will be understood from the foregoing that with the collar 16 securedto the shaft,

any rotatable movement of the inner racemember 10 will cause the ring 15and the placed a complementary eccentric flange 27 l on the collar 28.-

the one previously" described, any movement Fig. 2 is a similar View ofa modified f0rm sin le embodiment of this invention, it is has a flange18 which bore 19 to move so as to be eccentric to each other, therebybringin them into engagement and preventing further movement of theinner race-member'lO.

The outer race-member l1 issecured in a bore 20 in the housing 21 bymeans of a cover 22 which is screwed thereto. The end of the housing 21,and the outersurface 23 of the overhanging flange is concentric with Jthe axis of the shaft 13, and upon this bears a felt washer 24 which iscarried in a groove in the cover 22 so as to prevent dust and moistureentering the hanger box. V

This device supplies a simple and efiective means forpreventing rotationand'hence p undue wear between the shaft 13 and theinnerrace-member-IO.

In Figs. 2 and 4 is shown a modified form" of the device in which theinner race-member 25 is-provided at its outer end with a reducedeccentric end 26 about which is In this construction as in of the innerrace-member 25 relative to the centric surfaces. both of which aremounted upon the shaft 29, to 'lockthereby preventng further rotation ofthe inner race-meme ber 25 with respect to the shaft- \Vhile I haveshown and described but a to understood that it is capable of manymodifications. Changes therefore in the construction and arrangement maybe made which do not depart from the spirit and scope of the inventionas disclosed in the appended claims.

I claim: 1. In combination, an anti-friction hearing having inner andouter race-members and anti-friction elements therebetween, a shaftpassing through said inner racememher, and a member adapted to besecured to said shaft adjacent the inner race-member and having a flangeoverlying a part of said inner race-member, said flange and part havingcontiguous concentric surfaces which are eccentric to said shaft wherebythe inmi race-member is prevented from turning on said shaft.

2. In combination, an anti-friction bear- 105 ing having inner and outerrace-me shaft ber,

passing through said inner race-mema member adapted to be secured tosaid shaft adjacent the inner race-member and 5 having a flange overlrace-member, said flange surface eccentr ie to the shaf ying a part ofsaid inner having an mner t, a groove in the end of the innerrace-member, a snap ring in said groove concentric with the innersurface of said flange whereby the inner racee niember is prevented fromturning on said s aft.

CLARENCE T. OLSON.
